Chase Oliver:

If you’re selling a vacuum, don’t start by pitching its bells and whistles. Instead, sell a clean home. It’s the reason people look to buy a vacuum in the first place. Once you’ve established that you understand — or better yet, sympathize with — your customers’ needs it becomes easier to justify each feature by tracing it back to the product’s intent.

A good analogy for Jobs to be Done – people don’t buy for features, they buy to solve a problem in their life.
